Thunderbolt 3, 4, or 5 ports USB-C Thunderbolt 3, 4, or 5 connector. Thunderbolt 3 is a hardware interface developed by Intel. [75] It shares USB-C connectors with USB, supports USB 3.1 Gen 2, [76] [77] [78] and can require special "active" cables for maximum performance for cable lengths over 0.5 meters (1.5 feet). Compared to Thunderbolt 2 ...
Thunderbolt 3 Gen 2 and Gen 3 and the USB4 Gen 2 and Gen 3 modes use very similar signaling. However, Thunderbolt 3 runs at slightly higher speeds, called legacy speeds, compared to rounded speeds of USB4. [34] It is driven slightly faster at 10.3125 Gbit/s (for Gen 2) and 20.625 Gbit/s (for Gen 3), as required by Thunderbolt specifications.
The USB 3.1 specification takes over the existing USB 3.0's SuperSpeed USB transfer rate, now referred to as USB 3.1 Gen 1, and introduces a faster transfer rate called SuperSpeed USB 10 Gbps, corresponding to operation mode USB 3.1 Gen 2, [62] putting it on par with a single first-generation Thunderbolt channel.
Original Thunderbolt implementations have two channels, each with a transfer speed of 10 Gbit/s, resulting in an aggregate unidirectional bandwidth of 20 Gbit/s. [120] Thunderbolt 2 uses link aggregation to combine the two 10 Gbit/s channels into one bidirectional 20 Gbit/s channel. [121] Thunderbolt 3 and Thunderbolt 4 use USB-C.
The physical phenomena on which the device relies (such as spinning platters in a hard drive) will also impose limits; for instance, no spinning platter shipping in 2009 saturates SATA revision 2.0 (3 Gbit/s), so moving from this 3 Gbit/s interface to USB 3.0 at 4.8 Gbit/s for one spinning drive will result in no increase in realized transfer rate.
Thunderbolt 3 (40 Gbit/s) Alternate Mode with cables longer than 0.8 m requires active Type-C cables that are certified and electronically marked for high-speed Thunderbolt 3 transmission, similarly to high-power 5 A cables. [36] [39] These cables are marked with a Thunderbolt logo on both ends. They do not support USB 3 backwards compatibility ...
Full speed (FS) rate of 12 Mbit/s is the basic USB signaling rate defined by USB 1.0. All USB hubs can operate at this rate. High speed (HS) rate of 480 Mbit/s was introduced in 2001 by USB 2.0. High-speed devices must also be capable of falling-back to full-speed as well, making high-speed devices backward compatible with USB 1.1 hosts ...
Most Lightning devices only support USB 2.0, which has a maximum transfer speed of 480 Mbit/s or 60 MB/s. With USB 2.0, only one lane is in use at a time. [24] [25] Only the 12.9-inch iPad Pro (1st and 2nd generation) and 10.5-inch iPad Pro support USB 3.0 (now USB 3.2 Gen 1), which has a maximum transfer speed of 5 Gbit/s or 625 MB/s. [9]
